The following is a recent e-mail from a Polish citizen with a worthwhile consideration reguarding the polka-

I'm polish and when i surfed in the net, i found your's cours about Poland. I think that is very  good, but i found one error. Polka isn't polish dance, this is tipical Czech dance. Polish dances are: krakowiak, kujawiak, mazur, oberek, zbójnicki....
 
Best regards
